i played a few and the perks are pretty good really.
added driver/iron distance, easier ding/accuracy, stronger out of rough and sand and a lot of other perks i can't recall. i spend a ton of time on mobile while sitting with my mom during chemo treatments so have had time to unlock some stuff on it.
if you're a mobile player, they are worth it. 30 minutes at a time window for rewards and you're playing anyway so why not??
